PRQJECTILES FOR SMALL-ARMS.

To all whom, it-masy concern:

Beit known thatI, FREDERICK Wrens,

residing at Halfway Lodge; Esher in the county of Surrey, En land, have invented a certain new and usefulApparatus for Casting Projectiles for Small-Arms, of which the fol-i lowingis a specification.

This invention relates to an apparatus for! castin projectilesfor small-arms in-molds carrie by a mold-wheel, the mold-wheel car "v rying the .moldspast a nozzle Where a jet of molten metal isinjected into the molds and then around to a position where themolds are pushed outfor the purpose of delivering the cast projectile therefrom. l 1

Referring to the drawings, wherein I show a specific embodiment of my invention, and wherein like reference-numerals are used to designate the same. parts wherever they occur, Figure 1 is a vertical sectional view, partly in elevation, of one form of my apparatus; and Fig. 2 is a plan view thereof.

a is a vertical shaft on which the moldwheel I) revolves. The mold-wheel is pro-, vided with a suitable gear, which meshes with a worm c, driven from any suitable source of power and by which the mold is rotated.

, (1 represents passages bored in the shaft' 3 -for the circulation of cooling water throu h wheel I) is provided with passages (1, formed in the wheel b. T ea plurality of radial openings, in each of which is slidingly mount- V pivot being formed into projection g, in the arm f of the mold.

ed a,mold, the mold consisting of two parts .2 and f, whichare hinged together, themold being formed by the jaws on onesideof the pivot and the part at the other side of the arms by which thejaws areopened and closed in a mannerto be hereinafter described. On the upper end of the shaft c is mounted a cam, having the cam which engages witha notch out The cam, which is of the form best shown in Fig. 2, causes the mold as it is carried around by the wheel to move to and fro in the radial openings of the wheel. The cam is also provided with a camgroove h, which engages the free end of the arm of the part 6 of the mold and by the curvature of the cam causes the mold. to open and close as the mold is carried-around by the mold-wheel.

' '1' is an upright frame also carriedby the end of the shaft a, and on the top of this upright is fitted a slide 3', adapted to lide hori- ,zontally on the upright i, and from the slide pinion 1', having on its shaft 3; disk 8,

-, projectile is cast.

the shield is projects downwardly in front of the periphery of the mold-Wheel.

Z represents adjusting-screws,by means of which the shield can be brought to the proper position in relation to the periphery of the mold-wheel. In the center of the. shield I provide an orifice, into which projects a nozzle m, coming from a pump. Preferably this pump is of the type shown in my Patent No. 669,405, dated March 5, 1901, and n is the duct by which the surplus metal delivered by the pump is returned into the meltingpot p.

On a'boss of the mold-wheel b is fitted a gear g,Lwhioh is adapted to mesh with the provided with'fonr projections t.

The operation of my invention is-asfollowsz'When the mold-wheel is driven' in the direction of the arrow in Fig. 2. by'meansof the worm c, the molds are successively and graduall'y brought by the cams g and h from the protruded and 0 en position shown at the right-hand'side of Figs. 1 and 2 to the inward Having thus described my invention, what I claim as new, and desire to secure by Let ters Patent, is

1. in an apparatus for casting projectiles, the combination with a mold-wheel of. molds sliding radially therein, means for movingthe molds in and out in relation to the moldwheel, means. for forcing a jet of molten metal into the molds when they are in their retracted position, and means for thereafter moving the molds outward to deliver the cast projectile.

2. In an apparatus for casting projectiles, the combination with-a mold-wheel of molds sliding radially therein, means {pr moving the molds in and out in relation to "e moldwheel, means fhr forcing a jet of molten metal into the molds when they are in their retracted position, means for forming a condially cavity in the end of the ifor moving the moldsto deliver the cast proectiIe. y

3. In an apparatus for casting projectiles for small-arms,-.the combination with a mold-.-

wheel, of a seriesof molds carried by tha to move radially of the moldewheel adapted mold-wheel, each mold being composed of two parts ,hin ed together, means for moving the molds ra 'ally of the wheel, and means for opening the molds when they are in their outward position, and closing them as'they approach their castingosition'. v

.4. In an apparatus or casting projectiles for small-arms, the combination with a moldwheel, of a plurality of molds mounted raof the mold-wheel, a cam for movin the molds radially of the mold-wheel, and means for supplying to the molds molten metal under pressure when the molds are in their retracted position.

5. A. mold-Wheel, a series of scissor-shaped molds mounted in and arranged radiall of the mold-wheel and adapted to move radially projectile, and means thereof, with meansioremqyigg the molds into the mold-wheel. to outwardly to discharge a bullet, substantially as described.

- 6} In an apparatus for casting projectiles,

the combination with a mold-wheel, of a series of scissor-shaped molds mountedin the wheel, means for moving the molds radially of the wheel and means to cause the molds to open when moved outwardly and to close "when moved inwardly.
